It is from time to time also known as momentum diffusivity. Whereas Kinematic viscosity is the sort of viscosity that is computed by calculating the ratio of the fluid mass density to the dynamic fluid, viscosity or absolute fluid viscosity. The shearing stress between the layers of a no turbulent fluid which is moving in straight parallel lines may be defined for a Newtonian fluid. It is at a unit velocity while maintaining a unit distance apart in the fluid. dynamic viscosity coefficient is a measure of internal resistance. There are two related measures of fluid viscosity: Dynamic and Kinematic.Ībsolute viscosity i.e. Viscosity is a concept where fluid shows struggle against a flowing, which is being distorted due to extensional stress forces or shear stress.

The Prandtl Number - Pr - is a dimensionless number approximating the ratio of momentum diffusivity (kinematic viscosity) to thermal diffusivity - and is often used in heat transfer and free and forced convection calculations.
